ACTGOV Canopy Cover 2020 Statistics

ACT Canopy Estimate Statistics 2020 for blocks, divisions and road polygons are derived from the ACT Canopy Cover 2020 footprint dataset (available soon). The canopy dataset is derived from LiDAR (Light Detection and Ranging) data captured by Aerometrex and the ACT Government (available here) at 12ppm over the ACT and region in April 2020. This datasets provides the estimated % coverage of vegetation above 3m for blocks, division and road polygons current at 2021, and was completed by a collaboration between EPSDD and TCCS, ACT Government. The canopy coverage % is determined by the coverage of vegetation above 3m divided by the area of feature (e.g. block area). The total tree canopy cover estimate for Canberra for 2020 is based on the footprint of all urban divisions (suburbs): 22.5%. View this data in our ACT Canopy Cover 2020 Interactive Web App.

ACT Blocks, Divisions and Road Polygon data are available in the ACT Geospatial Data Catalogue https://actmapi-actgov.opendata.arcgis.com/. The ACT 2020 LiDAR point clouds (Aerometrex and ACT Government 2020) are available from https://elevation.fsdf.org.au/ (CCBY Licence).

Data lineage: This dataset is derived from the Light Detection and Ranging (LiDAR) data captured by Aerometrex and ACT Government over ACT in April 2020. The point clouds were processed by the ACT Government with ArcGIS to produce ACT Canopy Cover footprint for vegetation above 3m. Canopy modelling was completed at 1m resolution. The canopy footprints were then augmented to block, division and road polygon coverage statistics.

Coordinate system: GDA 2020 MGA Zone 55. Temporal coverage: April 2020 Update schedule: every 5 years

Caveat: Comparison of the ACT 2020 Canopy Cover to the 2015 is not comparable due to differences in methodology, including differences in resolution and point density, and time of year the LiDAR was captured. The 2015 data was captured in late Autumn, whereas 2020 was captured in early Autumn.
